Module: wibox.widget.checkbox

A boolean display widget.

If necessary, themes can implement custom shape:

Usage example

wibox.widget {
    checked       = true,
    color         = beautiful.bg_normal,
    paddings      = 2,
    check_shape   = function(cr, width, height)
        local rs = math.min(width, height)
        cr:move_to( 0  , 0  )
        cr:line_to( rs , 0  )
        cr:move_to( 0  , 0  )
        cr:line_to( 0  , rs )
        cr:move_to( 0  , rs )
        cr:line_to( rs , rs )
        cr:move_to( rs , 0  )
        cr:line_to( rs , rs )
        cr:move_to( 0  , 0  )
        cr:line_to( rs , rs )
        cr:move_to( 0  , rs )
        cr:line_to( rs , 0  )
    end,
    check_border_color = '#ff0000',
    check_color        = '#00000000',
    check_border_width = 1,
    widget             = wibox.widget.checkbox
}

Usage example

Usage:

    wibox.widget {
        checked       = true,

Add a new awful.button to this widget.

Parameters:

  • button awful.button The button to add.
:emit_signal_recursive (signal_name, ...) · Inherited from wibox.widget
Emit a signal and ensure all parent widgets in the hierarchies also forward the signal. This is useful to track signals when there is a dynamic set of containers and layouts wrapping the widget.

Parameters:

  • signal_name string
  • ... Other arguments
:emit_signal (name, ...) · Inherited from gears.object
Emit a signal.

Parameters:
